position-paragraph

Returns the paragraph number of the paragraph containing a given position.

Calling this method may force the recalculation of location information if a maximum width is set for the editor, even if the editor currently has delayed refreshing (see refresh-delayed?). If the editor is not displayed and the editor has a maximum width, line breaks are calculated as for line-start-position.

• (send a-text position-paragraph start at-eol?) -> exact non-negative integer
      start : exact non-negative integer
      at-eol? = #f : boolean

  See End of Line for a discussion of at-eol?.
